Starting today, the Lumia Windows Phone 8 smartphone family will receive the Lumia Cyan software, the new Windows Phone 8.1 update and Lumia features upgrade that will make your Lumia an even more personal, fun and indispensable part of your life.

Windows Phone 8.1 is a must-have - those of us who have been running the developer preview thing know that quite well. The update will come to Windows Phone 8 Lumia devices over the coming weeks in Microsoft's usual staggered rollout. I haven't seen any information yet regarding non-Microsoft Windows Phone devices.
